SPECIFICATION forming partof` Letters Patent No. 291,466, dated January l, 1884.

i Application filed June (i, 1883. (Model.)

To all whom it may concern: t i

Beit knownthat I, GHAs.R.BioKnoRD, acitizen of the United States, residing at Elyria, in the county of Lorain and State of Ohio, have invented a new and useful Door-Check, of which the following is a specification. i My invention relates to improvements in door-checks which are automatic and vreversi- "ble, being actuated by means of a suitable io i the mechanism illustrated in the accompanyspring. I attain,... these objects by means of ing drawings, in which- Figure lis a perspective view of my invention. Fig. 2 is a plan view. Fig. 3 is a broken sectionof the outer end of the stop,

and Fig. 4 is a sectional view of Fig. 2 in the Similar letters refer to similar parts throughout the several views.

The letter A isa door-stop of any suitable material and size, provided with a recess or slot of suitable width and depth cut transversely out of `its upper side.

B represents a catch of suitable material and size,and of similar form to that represented in the drawings.

c is a pivotal screw or pin connecting A and B, so constructed as to allow B to freely turn. j i

l) represents an escutcheon, fastened to a door, into which `B may securely catch.

E is a rubber cushion, fastened in the end `of A, for the purpose of breaking the jar of 5o spring a.

4 said stop A.

a is a suitable spring, so constructed as to operateagainst aprojection on the catch B, and constantly exert a pressure forward to said catch B. Y

d is a suitable projection on the catch B, for the purpose of retaining one end of the `The stop A is securely fastened to the baseboard or anysuitable place, and so adjusted that the nose of the catch B will engage with `the escutcheon D. The spring a; and pin e,

operating against thewalls of the slot or recess g, hold the catch B in line with the edge` of the door. The door, being forced back against the stop A, strikes the inclined end or nose of the catch B, and forces it back until it reaches the hole in the escutcheon, when the action of the spring a forces the outer end of the catch forward into said escutcheon, and retains it there until forcibly removed. The pin e is so placed that it allows the free movement of the catch B in certain prescribed distances, and by striking against the sides of the recess g prevents the catch B from being forced so farback as to injure 'the spring a,

and prevents said spring a from forcing the` t catch B so far forward as to be out of position for receiving the door. The gravity-pin h is set in line with the path of the pin c, and is so placed that when the catch B is thrown back, as seenin the dotted lines, Fig. 2, by raising said pin 7L up it will be just back of the pin e. The frictional resistance of the pin e and of the pin h in its hole, caused by the force of the spring ,retains it in its position,whereby it holds said catch back entirely out of use, when so desired. By pressing back on the catch B the gravity-pin h is freed from its contact with the pin e, and drops back into place, allowing said catch B again free movenient and operation.

What I claim as new, and desire to obtai Letters Patent of the United States for, is

ln a door-check, the rigid pin e and gravitypin 7L, in combination with the spring arm or catch B, screw c, spring c, and stop A, for the purposes above set forth, and substantially as described.
